\VILLIAM E. SEFTON, OF CANTON, OHIO.

PLOW-CLQEVIS.

SIECIFIGATION forming part of Letters Patent No. 408,857, dated August 13, 1889.

Application filed May 10, 1889. Serial No. 310,226. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. SEFTON, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Plow-Clevises; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon, in which Figure 1 is a View of aportion of a plow-beam, showing clevis and its different parts properly attached. Fig. 2 is a side elevation showing the draft-link locked. Fig. 3 is a detached view of the draft-link, showing the swivel properly attached. Fig. 4 is a detached View of the locking-lever. Fig. 5 is a detached view of the draft-link bolt.

The present invention has relation to plowclevises; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claim.

Similar letters of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, A represents a portion of a plow-beam, to the front or forward end of which is securely attached a crown-head B by means of the clampingbolt a. This crown-head B is provided with the teeth I), which teeth are located upon the sides and rear of the crown-head B. To the beam A is pivotally attached the draft-link C by means of the clamping-bolt c. To the front of forward end of the draft-link U is attached the swivel D, which swivel is for the purpose of attaching the doubletree-clevis. One end of the draft-link O is provided with the round aperture d, which is for the purpose of receiving and holding the eccentric d. The opposite end of the draft-link C is provided with the heart-shaped aperture c. The locking-lever E is located, as illustrated in Figs. 1 and 2, and when it is desired to detach the lugs f from the teeth I) the free end of the locking-lever E is forced away or from the draft-link C until the catch g is released from the rib 71 when said locking-lever is free to be elevated to a distance sufficient to detach the lugs f from the teeth I), at which time the draft-link C is free to be adjusted to any desired point within the limits of the teeth Z). WV hen the draft-link C is brought to the desired point of adjustment, the lockinglever E is forced or pressed downward at its free end until the catch 9 comes in contact with the rib 71, thereby securely locking the lever E and the draft-link C.

It will be seen that as the locking-lever E is forced downward the draft-link C will be carried forward by means of the eccentric d. It will also be seen that by providing the heart-shaped aperture 6 the clamping-bolt 0 will be securely held at each end, the cocentric d securely holding the opposite end of said bolt 0, thereby securing a sure and firm engagement of the lugs f with the teeth I).

It will be understood that the eccentric d is to be formed integral with the locking-lever E; or, if desired, said eccentric may be formed separately and securely attached to the locking-lever E. The teeth a are formed somewhat longer than the teeth I) for the purpose of preventing the draft-link C from falling below the crown-head B when the lugs f are detached from the teeth 1).

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the beam A, provided with the crown-head B, having the teeth I), the draft-link 0, provided with the round aperture (Z and, the heart-shaped aperture 6, the locking-lever E, provided wit-h the eccentric d, and the catch g, adapted to engage the rib h, and the lugs f, adapted to engage the teeth Z), substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

\VILLIAM E. SEFTON.
